User blog comment:SquidSpooks/Why is Morrison black in DMC5 but white in the anime?/@comment-7515480-20181018152049

Because it's always easier and depending on who you ask, lazier, to raceswap an existing character, as opposed to introducing a new one. With that being said, Morrison is a minor character who's only appeared in the animated series so I can understand why they decided to change him of all characters. You wouln't even know about him if you haven't seen the anime.
